The dummy signing driver implements the most rudimentary form of signing. No pre-shared key is used, nonce is simply incremeted each turn and signature is only calculated on the fist byte using data XOR nonce. This driver is intended for library debugging and sensor network integrity verification (signed messages will force the radio to transmit all 32 bytes of data). It does check SIGNING_IDENTIFIER byte to avoid illegal mixing of signing backends in the network (as seen by this node) and it does verify proper execution order on the API. The dummy driver rejects all other signing backend protocols. Signing backend is selected in MyConfig.h
